Everyone knows fatigue is dangerous and costly.

But what to do about it? There haven’t been tools to make fatigue risk management decisions easy. Until now.

Fatigue Meter by Pulsar Informatics

How does it work?


Our systems integrate with your scheduling and logging systems to import your workers’ duty schedules. You can analyze historical data as well as run scenarios to plan future schedules.

Import work schedules from your scheduling application.


Fatigue Meter’s algorithms apply the latest, peer-reviewed science to analyze your operational data. Our proprietary Off-Duty Behavior model estimates individual sleep periods and fatigue levels. Then predictive analytics give you a picture of each worker’s expected fatigue profile several days forward. Download more information about our fatigue model.


Our user-friendly dashboard lets you explore options to mitigate fatigue risk in upcoming schedules. Once your team decides on the best approach, you can proceed to implement the necessary changes in your scheduling system.

Spot fatigue risk and make the necessary scheduling changes before something happens


Whether it’s real-time monitoring or developing future work schedules, our tools help you maintain a safe and high-performance operation. Use our custom performance metrics to grade the safety of future schedules and evaluate the impact of planned process improvements.

Spotting fatigue risks ahead of time allows you to fine-tune upcoming schedules to maximize safety.

Originally developed for NASA and DOD, our technologies offer the best in security, performance, and ease of use.

“We use the Pulsar Fleet Insight as an integral segment of our overall Fatigue Risk Management System. Operating an average of over 125 flights per day, we use Fleet Insight to monitor pilot fatigue risks fleet wide. In addition, we effectively use it to prospectively evaluate potential flight crew fatigue risks on targeted trips. Specifically to evaluate the need for flight crew fatigue mitigation steps for planned trips that operate in the crew’s window of circadian low (WOCL). It works seamlessly with the FOS scheduling tool and provides easily interpreted fatigue data to help make effective fact based decisions. ”
